Change Animation Playback Speed Dynamically

So, the mod im creating adds a bunch of RPG aspects to the game; Agility being one of them which will affect attack speed,

is there a way for me to play the attack animation at a different speed for different players for one animation with the speed being determined by your agility stat

i would like to do this without making 100 of the same animation

im using blockbench and the geckolib plugin
